Frontend Engineer

ASI's mission-critical technology powers decision-making across aviation, defense, energy, and other critical infrastructure domains. Backed by top-tier investors including Andreessen Horowitz, Spark Capital, and Renegade Partners, ASI delivers operational decision superiority—compressing days of analysis into seconds of action. ASI is leading the way and pushing the boundaries of what’s possible.

As part of our product engineering team, you will develop user interfaces that support mission-critical operations, enabling users to monitor and predict flight trajectories across complex, large-scale air traffic systems. You'll work closely with our design team to craft performant, map-driven web applications that help users make real-time decisions based on high-density, geospatial information.

• Proficiency in JavaScript/TypeScript, React, and CSS.

• Experience building complex, map-based web applications with Mapbox, Maplibre, or Google Maps, with a focus on real-time rendering of multiple interactive features and overlays.

• Familiarity with WebGL, WebGPU, or ThreeJS for accelerated graphics rendering and WebAssembly (WASM) for enhancing application performance.

• A bias for action. When you see a problem you solve it.

• Ability to writing fast, efficient, and maintainable code.

• Strong attention to detail and a passion for great user experiences.

• Proficient in leveraging modern LLM tools to accelerate development workflows and enhance code quality.

We look at the interview process not as a screening or test, but rather as an opportunity to simulate what it would look like working together. We build the interview process around you.

ASI works with export controlled technology and restricted U.S. Government data, including on contracts mandating U.S. immigration status and location restrictions for performing personnel.
